TECHNICAL FIELD

The present invention relates to the field of chemical productsapplication for the agriculture, pestilence, plague, or insects control,or other chemical applications in determined areas to receive thesechemical products such the agrochemical application made by manned orunmanned vehicles, being these vehicles aerial, land or watercraft withthe aim of treating soil and/or seeds and/or plants.

BACKGROUND OF THE INVENTION

Agricultural aviation is one of the possible applications of chemicalsthat has numerous advantages, such as: no contact with the ground, thusavoiding the kneading of culture and soil compaction; not cause stressin plants; early entry in the area, even after rain and immediatecontrol of pests and diseases.

However, aerial application has its disadvantages, such as: disrespectto the contracted application range, causing the loss of efficiency ofpesticides and exceeding the area limits; these limits when are notrespected, can generate application on surrounding areas, permanentprotection areas (APP), schools, water sources and others causingnumerous losses to the environment, people and the producers.

The current application of chemicals made by tractors also presentsproblems with regard to failure to apply in relation to the area wherethe product should be applied and it was not applied by a tractor drivererror and also problems with excess or lack of such chemical productsapplication because such control is also made by the tractor driver.

Thus, both the land applications as the aerial applications of chemicalsproducts used in agriculture, or even for the treatment and/or controlpests in rural or urban areas, it is necessary to control both thevehicle's path used for the dump chemical product as well as the timingand amount of chemical product to be applied in a certain area.

The present system ensures that the land and the aerial space of thefarm is traversed by the vehicle in the most efficient manner followingan optimized predetermined path in opposition to a manual operation ofan agricultural vehicle may result in gaps or the non-optimal use offuel or agricultural materials.

SUMMARY OF THE INVENTION

One of the objectives of the invention is to provide a system and amethod that identifies the following factors in the application ofchemical products: what was the range of application used, if the limitsof the pre-established application areas were respected, if applicationswere made duplicate, and if has applied the correct amount of product.

The system generates reports with all data above in hectares, thusallowing analyzing and quantifying the losses safely. When the report isgenerated to the producer, the system provides all exemplified dataabove. Another feature is the audit of the correct costs of theapplication of chemical products by means of vehicles in a certain area.

The system allows a clear and safe identification of the details of thelosses arising from the misapplication of the chemical products, such asaerial and/or land applications of agrochemicals.

The system aims to solve the problem of product losses in the process ofapplying of chemical products in a certain area in a simply way.

The system allows the registration of companies that distribute productsapplied by air, land or water, the pilots (in the case of mannedvehicles) and vehicles (such as aircraft) that provide services to theproducer. It also allows the registration of all the plots of theirgeoreferenced properties by importing GPS files of the vehicleresponsible by distributing the agrochemical product.

Such system allows the monitoring of the distribution of chemicalproducts by manned or unmanned land, aeronautical, or water vehicles, inrural or urban areas, as well as in forest areas.

The present system can also be applied in the application of seeds andany other products to being distributed by means of vehicles in apredetermined and georeferenced area.

The vehicle guidance system involves the reception of a positionindication signal which allows a control unit on the vehicle todetermine its position. Commonly, the position indication signal istaken from a Global Navigation Satellite System (GNSS) satellite basedpositioning system such as the American Global Positioning System (GPS)and/or the Russian GLONASS System and/or the European Galileo systemsignal or the more accurate differential satellite signal.

The system generates the application reports of chemical products basedon files generated by GPS or similar system embedded in the vehicle.Thus, the report states in which plots the chemical product wereapplied, the products used and all the statistical results of theapplication.

The system performs hundreds of topographic calculations and displaysthe report ready in seconds allowing the producer to view the results ona computer screen, laptop, cell phone, palmtop, tablet, or any devicethat has remote access to the internet. This report can be saved orprinted.

The system has the following features:

-   -   Application Management: through the system it is possible to        have confidence that the product application range contracted by        the producer was respected by the pilot and all the limits of        the areas were respected;    -   Area and Cost control: The system provides an individual control        for area informing, by report, which products were used, the        costs of application and efficiency of the same;    -   Remote control: even if not present in the property, the        producer receives notifications on your smartphone or any other        mobile device with Internet access with the application report        of these areas;    -   Control by property: regardless of the number of areas, the        release of information in the system will be separated by        properties or pre-established public areas enhancing the        management of such areas;    -   Printed reports with QR-Code: the system allows printing reports        with QR-Code that can be read by any smartphone or any other        mobile device with internet access allowing access to the report        in detail. Such reports can be provided with any technology that        allows quick access to the information from the system; and    -   Corrective measures: These measures are generated by the        vehicle's GPS (or similar device) during application thereby        achieving images of the flight or path of the aquatic or        terrestrial application, and if it detects any product        application error in the established area, corrective measures        can be taken remotely by the system.

This application can be accessed by desktop computers (4) running webbrowsers. In this desktop (4) access it is possible to upload the GPScollected files containing all the information necessary to generate thefinal application report (7).

This application is also accessible by mobile devices (5) such assmartphones and tablets, but it has limited features since it is notpossible to upload the GPS files directly from mobile devices. In thiscase, the user is able to view previously generated reports as well asother related information.

A GPS device from where GPS files (6) are collected by the device usedin the application method. It may be generated by GPS embedded intoagricultural aircrafts or tractors. These files are used as input datafor generating the final application reports (7).

The final product of this process is the final application report (7),which contains all detailed information about how much product wasapplied and in which areas (plots) on the ground. It also contains afinancial information about the relation between products/dosage/costsfor this application.

The report also shows a success rate for the application. The reportinformation's are: property name, pilot, aircraft, total costs, successcosts, application's beginning/ending date and time, average applicationspeed, application spray width, total traveled distance, total plotsarea, total application area, external application costs, applicationrate, overlap area, success area, external area, not covered area andsuccess rate.

FIG. 2 is a detailed step by step chemical product application andreport generation flow. It describes how all the needed information isgathered and how the calculations are made in order to generate thefinal report (7) that constitutes a method for control and audit thechemical products application made by a vehicle.

In the step (101) the process starts by a pre-processing routine toinitialize the application variables.

In the step (102), the user is prompted to inform which plots thisapplication was supposed to be done. Next, the system will load, fromthe desktop web application (4) to the Perfect Flight Application (1)through the internet (3), each plot polygon area, based on previouslygeoreferenced imported files.

In the step (103), the application's sprays polygons are loaded from theGPS input files (6). The raw GPS log files, of the embedded GPS in thevehicle, is acquired from the GPS device by using a flash drive directlyconnected to the device's USB port and the user must use the exportfunction of the GPS embed system to copy the files to the flash driveand after that the user upload the GPS input files (6) to the PerfectFlight Application (1) from the desktop web application (4).

In the step (104), the chemical product application traveled path isalso loaded from the GPS input files (6).

In the step (105), the information about company, pilot/driverinformation are also collected by the user.

In the step (106), the list provided by the user containing each appliedproduct, dosage and costs is also loaded into memory for the financialreport.

In the step (107), with all needed information collected from thedesktop web application (4) by the user and loaded into memory at thePerfect Flight Application (1), the system can now start processing theapplication report (7).

In the step (108), the application beginning/ending date and time areread from the GPS input files (6).

In the step (109), the application's average spray width is loaded fromthe GPS input files (6).

In the step (110), the vehicle traveled distance is calculated by thetraveled path from the GPS input file (6).

In the step (111), the chemical product application's average speed iscalculated based on the GPS input file (6).

In the step (112), the system generates a new polygon based on the unionbetween all the applied plots informed by the user. This is the supposedgoal target area for the application and all next calculations are donebased on this resulting polygon.

In the step (113), the area in hectares is calculated for this resultingpolygon.

In the step (114), the system also generates a new polygon resulting bythe union between all chemical product application sprays.

In the step (115), the area of the resulting application spray polygonis calculated.

In the step (116), calculate the resulting polygon for the overlapapplication spray areas. The overlap area id caused when the applicationis done more than twice in the same region, causing waste of appliedproducts.

In the step (117), calculate the resulting polygon of no applicationarea. This indicates areas that were not covered by any sprayapplication.

In the step (118), the system can now calculate the successfully appliedpolygon. This indicates areas inside the plots informed by the user thatactually were covered by the application.

In the step (119), the external application polygon is calculated andindicates areas outside the plots indicated by the user. It alsorepresents waste of applied products.

In the step (120), based on all the calculated area information, thesystem can now generate the financial report, which indicates the totalcost of this application and the cost represented by the success andwasted areas, as well as the cost per applied hectare.

In the step (121), the final report (7) is now processed and ready to bedelivered to the end user, even by desktop (4) or mobile (5) access.

In the step (122), the system will save this report into the applicationdatabase (2) in order to reduce loading time the next time the usertries to review this report.

This is important, since the processing of the report involves heavycalculation.

In the step (123), a new identification hash code is generated for thereport (7) and a QRCode is also created based on this hash code. TheQRCode is displayed in the print form of the report (7). It is used toeasily reopen the application report (7) in the computer (4) or mobile(5) device by simply reading the printed QRCode on the paper report (7).Reports can also be exported as PDF (Portable Document File) files foroffline access outside the system.

In the step (124), all the resulting calculated polygons during thegeneration process are saved into application database (2) files in theserver's file system. These files will be opened for later reviewing ofthe report (7).

In the step (125), the final calculated information is saved in theapplication database (2) which provides fast access to the mostimportant information of the report (7) and also provides ease for theend user to find and filter generated reports.

the user, step (305), must register thelist of each chemical product to be applied, dosage, spray width andrate, and costs; the application (1), step (306), calculates thechemical product application vehicle (9-12) pathway and its averagespeed; the application (1), step (307), sets the vehicle control unit(8) with the chemical product application parameters such applicationpathway, average speed, dosage, spray width and rate; after all thechemical product application parameters be set the vehicle (9-12) isready to begin the application, step (308); once initiated the productapplication, step (309), the application (1) monitor the GPS (6)information, by a pre-configured time, and, with this information,compare the vehicle (9-12) position with the application pathwaycalculated in the step (306); if, step (310), the vehicle is going inthe correct pathway, the vehicle (9-12) maintain its way, otherwise, theapplication (1), step (311), send a command to the vehicle control unit(8) to correct the application pathway; based on the GPS (6)information, in the step (312), the application (1) compare the chemicalproduct application parameters that are being sprayed with the pre-setparameters from step (307); if, step (313), the applications parametersthat are being sprayed are not in accordance with the parametersestablished on step (307), the application (1), in the step (314), willcorrect the application parameters to the parameters from step (307),otherwise, will continue with the application; finally, in the step(315), the application (1) compare the GPS (6) position information andcheck if the application pathway arrived to the end position; if, step(316), the end position was achieved, the chemical product applicationis stopped and the vehicle (9-12) returns to the base, step (317), andthe application (1) process the steps (101) to (126) to generates theapplication report (7), otherwise, continue with the chemical productapplication.
